A customer requests service to prepare and record a contract. A copy of the new contract is sent to the customer. A copy of the contract is stored in the contract file.
The operations office sends an hours worked report for personnel to be recorded in the system of the number of hours worked. Hours worked data is stored in the Hours Worked file.
Using the information from the contract and the hours worked file a monthly statement is prepared. The monthly statement is sent to the customer, and is used to update the Accounts Receivable master data file. A report of contracts not billed (for the month) is sent to the Sales Office.
Problem 4-3 Narrative:
A customer sends an order form to the central sales office. Central sales office keys the order into the computer. The computer reviews the order (using data from the Sales Order master data), checks the customers credit (using data from the Accounts Receivable Master file and the Customer master data file) and logs the order in the System log. A daily event log is printed at the end of the day. An accepted order is displayed on the Central Sales office screen. The clerk then manually logs the sales into the clerks log. At the end of the day the clerk compares the log book against the Daily Event Log report. Any discrepancies are manually followed up. The computer then checks inventory (using the Inventory Master data file), records the order (using the Sales Order Master data file) and prints the packing slip in the regional warehouse. The packing slip is sent to the warehouse where the order if filled and a filled order report is created. The warehouse supervisor manually enters the order number and quantities shipped into the computer from the filled order report. The computer records the shipment, updating the Sales Journal, Sales Order master data file, and the Inventory master data file. The computer displays the accepted order to the warehouse supervisor. The supervisor then files the report numerically.
